What the description says clocks measure
According to the description, epigenetic clocks are tools that estimate biological age by measuring patterns of DNA methylation linked to aging. DNA methylation is described as one of the most studied biomarkers of aging because it reflects chemical changes that can influence how genes are expressed over time. The description also lists biological age versus chronological age among the topics covered.

Healthspan, lifestyle and longevity science in the description
The description says epigenetic clocks may offer insight into healthspan, metabolism, inflammation, lifestyle factors and healthy aging. It lists how lifestyle may influence methylation patterns and the role of epigenetic clocks in longevity science among the topics covered. These are described as possible insights, not as established effects of any lifestyle change.

Stated limit: no exact lifespan prediction
The description states that epigenetic clocks do not predict exactly how long someone will live. It says they can help researchers and individuals better understand how aging may be measured at a molecular level. The description also promotes a supplement shop and asks viewers to subscribe; these are promotional elements, not evidence about clocks.
